○ Reduction of inundated buildings from flood by the effect of the Metropolitan Outer Underground Channel
→Approximately 7,000 buildings (from 1975 to 1984) →Approximately 50 buildings (from 2005 to 2014)
○Kasukabe City could be designated as an “Industrial Designated Area” in 2003, thanks to this Underground Channel.
○28 businesses (warehouses, shopping centers) were newly located in this area thanks to the Channel

• The elevation of cities in Japan is lower than the flood water level of rivers. • There are many steep rivers in Japan compared with rivers in foreign
countries.

Challenges for “smart use of infrastructure”
• Under these limited conditions, Japan proactively has been selecting
“smart use of infrastructure” instead of “expanding it”.

Reduction through preventive maintenance and of new technologies.
○ To prevent further acceleration of the deterioration of infrastructures due to their aging, MLIT has been intensively conducting inspections, diagnoses, etc.
○ MLIT is aiming at establishing a preventive maintenance-based maintenance cycle to reduce and level the maintenance cost.

Our Challenges and Strategy
1. “Revolution in Construction” to be realized (strategic
management, long-term plan, prioritizing effective stock effect, i-Construction)
2. Introduction and utilization of various funds (national, local,
PPP/PFI, charge, fare, JOIN, etc.)
3. Preventive and Strategic Maintenance (maintenance cycle,
maintenance industry, introducing robot in the fields, etc.)
4. Japanese Contribution for international fields (quality
infrastructure, technology transfer, capacity building, PPP, etc.)
Important strategy for future Infrastructure
A) Economic and Effective use of infrastructure and Preventive and Strategic Maintenance
B) Investment of Infrastructure Development must be recognized as basic needs for development
